Solar cells and their teachnoleadges

The history of solar cell development is briefly outlined, and the properties of the sun and solar radiation are reviewed. Properties of semiconductor materials that are important in the design and operation of solar cells are reviewed. The physical mechanisms involved in the generation and recombination of excess carriers are discussed and the basic equations of device physics are given. Both the dark and illuminated properties of p-n junctions are analyzed. Energy conversion efficiency limits are discussed for the photovoltaic process as well as the effects of various nonidealities on efficiency. Techniques for measuring the efficiency of photovoltaic devices are also described. The standard technology for making silicon solar cells is reviewed, and improved silicon cell technology is discussed. Considerations relevant to the detailed design of silicon cells are discussed. Several alternative device concepts are outlined and the structure and properties of solar cells made on some of the more developed alternatives to single-crystal silicon are discussed. Concentrating systems and photovoltaic systems components and applications are described. The design of stand-alone, residential, and centralized photovoltaic power systems are discussed. 

Solar cells and their applications

Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series and parallel circuits or series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series connected cells) causing substantial power loss and possible damage because of the reverse bias applied to the shadowed cells by their illuminated partners. Strings of series cells are usually handled independently and not connected in parallel, though as of 2014)individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.

Q:What is the working principle of a solar cell?
The simplest way to explain this is : A solar cell converts the sun's energy into electricity.
Q:How many years should I spend in the solar cell industry to be a good solar cells sales person?
Personally, I think 4 years will be good enough to be a really good solar cells sales, and you can accumulate a lot of client based and resources.
Q:Is the Photovoltaic Cells cheap to buy?
If you are determined to get the solar cells to generate the power for you, Photovoltaic Cells are one of the cheapest things you can get.
Q:What's the benefit of using a solar cell?
It can help avoid the greenhouse effect.
Q:How can I explain to my 10 year old daughter what solar cells are?
Solar cells are the cell that can collect the solar energy from nature.
Q:How to explain to students how the solar cells are made?
Purifying the silicon is the first step to make solar cells.
Q:Can anybody tell me how to make a solar cell at home?
To make a solar cell at home, you need to have things like these : Thin copper sheeting, Metal shears an emery cloth, etc.
Q:How does a solar cell raise industrial efficiency?
Solar Cell Efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into another more useful form, namely electricity.
Q:Is there any easy way to make a solar cell? I want to make a DIY solar cell with my child at home.
If you know the principle of solar cells, it can be easy for you to make it yourself.
Q:What is the solar cells market in China?
The Chinese market is booming, but the solar cells' market was developed 8 years ago. It was supported by the Chinese government before because the whole country has been aiming at saving energy and protecting the envionment.
Our company is a High-tech enterprise, who is professional on manufacturing on solar photovoltaic products. We mainly produce the solar module and system. Our annual production capacity of solar module is 50MW.Meanwhile,we also undertake the design, installation and serviceonbothon-grid & off-grid system for home and power plant.
